Lena Metlege Diab says she is seeking the opinion to determine if the abolition of the electoral districts of Clare, Argyle and Richmond violates the Charter of Rights and Freedoms.
Legislation altering the boundaries was introduced in 2012 after the Electoral Boundaries Commission recommended they be redrawn.
That prompted legal action by the Acadian Federation of Nova Scotia, which claims the districts are constitutionally protected and help ensure Acadian representation in the legislature.
The federation wanted the province to refer the legislation directly to the Nova Scotia Court of Appeal as a constitutional issue, but resumed its legal challenge after the process ground to a halt.
No one from the federation was available for comment.
